The Trump White House is rumored to be working on a beefed-up open access mandate. The potential executive order would require all scientific papers that are based on federally funded research to be made available online free of charge as soon as they are published. That would supersede a 2013 rule issued by the Obama White House that required federally funded papers to become freely available one year after publication.

The White House hasn't actually announced the new policy yet, but the rumors were enough to get the attention of scientific publishers. Last Wednesday more than 100 publishing organizations signed a letter calling on the Trump administration to scrap the proposal.
